To all whom it may concern:

lBe it known that I, MonnUcH L. KAPLAN, a citizen ofthe United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Electric Battery Lamps, of which the following Y is a specification.

The invention pertains more particularly to a. class of electric battery lamps ssessin a battery and a miniature electrlc lamp.

bu b and adapted to stand on a table or the like. The cb]ect of my invention is to simpliy, cheapen and extend the use ofelectric battery and candle lamps and to provide an electric candle lam comprising two main units, to-wit, a vertlcal plural-cell battery and a cap or top. member detachably applied thereto and carrying the lamp bulb. In carrying out my invention'll extend the negative pole of the lower cell of the pluralcell battery to the'upper end of the battery and construct the cap to pass into electrical engagement with said negatiye pole on the applicationof the cap to position over the battery. The lamp bulb carried by the cap has one terminal in electrical connection, through-the ca with the negative pole of the battery an the other terminal 1n electrical connection with the positive element of the upper cell of the batter The lamp bulb may be used as the switch for makin and breaking the circuit said lamp bul when screwed upwardly breaking the circuit and whenl screwed downwardly, completing the circuit and causing the lighting of the lamp. When the batte has become exhausted, the cap is removed t erefrom and placed upon a new battery, thus restoring the candle lam for further use.' ln accordance with my invention l dispense with the metallic casings which usually receive the battery of electric candle lamps and pro'- vide a candle lamp consisting essentially of the. plural-cell battery and the detachable cap or dome or like top member, the cap loeing e uipped with a socket to receive the ulb and, when necessary, a conduc-y lamp tive filler interposed between the lower terminal of the lamp bulb and the positive element oi'- the battery.

My invention may be carried into ehiect in several modified forms, two ci which li have illustrated in the drawings.

:The invention will be 'fully understood from the detailed descri tion hereinafter presented, reference bein ad to the accompanying drawings, in which:

Fig. 1 is a central'vertical section through an electric battery lamp constructed in accordance with and embodying my invention;

Fig. 2 is aside elevation of the battery separated from its exterior covering material and the superimposed ca Fig. 2 illustrating the battery within its pastebeard carton and showino' the manner of connecting the negative pole of the lower cell oi the battery with a suitable contact above the battery to be engaged by the cap;

lfig. i is a detached top view of the battery and its enclosin pasteboard carton;

A `ig. 5 is a detach vertical section of the cap, aken at a right angle section ci Fig. 1, an

. Fig. -6 is a vertical section through the upper portionof an electric battery lamp embodying 'a modification of my invention.

In the dra-wings, referring to Figs. 1 to 5 inclusive, illustrating one emlmdiment'oit' my invention, 10, 11 designate the cells ci the battery, one cell bein placed above the other in series and the who e constituting a vertical plural-cell battery. The negative or zinc pole of the cell 11 engages thecarbon pole of the cell 10, and said cells in the completion of the battery are enclosed in a pasteboard cylinder or the. like 12 which insulates and keeps the celle together and permits them to be handled as a si le battery. rlhe cells 10, 11 are slip d endwise into the c linder 12, which snug y receives said cells.

he cylinder or carton 12 is ot customary durable stiff character, except that in the present instance l extend it above the upper end of the battery to receive a superimposed cap or dome' 13 having in its upper end a threaded depending metal sleeve 1li, which may be secured to the cap or dome 13 by a line of' solder 15 or termed integrally therewith and receives the neck ot the usual miniature lamp bulb it. The sleeve 1t ie, ae usual, in electrical connection with one terminal o? the bulb f The cylinder or carton 12 is provided est opposite sides et ite upper and and' aber@ leo mit

Fill@ terial and serve to receive and .interlock with a lower sleeve portion 18 of the cap or dome 13, said sleeve ortion 18 being provided with lbayonet s ots 19, as shown in Fig; 5, to be engaged with the pins 17.

The negative pole of the lower cell 10 is carried upwardly above the battery by means of a conducting wire 2O which 1s soldered, at 21, to the4 zinc of the cell 10 and'at its upper end is soldered, at 22, to the adjacent pin 17.

The cap or dome 13 is preferably made of candle sha saidcap or dome in its upper portion being of general conical outline and having sides which curve downwardly and outwardly to an annular shoulder 23 formed by beading-the interior of the cap below its upper section. The annular .beading 23; provides a groove to receive the edges of a disk 24 of -ibre or other insulating material and likewise imparts a finish to that portion of the cap or dome which is directly above the upper edge of the cylinder or carton 12. The annular shoulder 23 constitutes a dividing line between the upper conical shaped portion of the cap or dome 13 and the depending` sleeve or skirt portion 18 of said cap or dome.

The disk 24 has secured upon its upper and lower sides by rivets 25, hollow metal caps 26, 27 which correspond with each other and are flanged to engage and be riveted to the disk 24. The disk 24 and caps 26, 27 constitute a conductive filler which I apply within the cap or dome 13 so as to bridge the space between the lower terminal of the lamp 16 and the positive element 28 of the battery cell 11. The negative pole of the battery is connected by the wire or conductor 20 with one of the pins 17 and hence is in circuit through the cap or dome 13v with the sleeve 14 and .the neck or one terminal of the lamp 16, while the positive element 28 of the battery is in electrical connection through the caps 26, 27 with the lower terminal of the lamp 16.

vIn assembling the parts of the electric. battery lamp, the bulb 16 may be screwed into the sleeve 14 and the ca or dome 13 may, after receiving the dis 24 and its parts, be appliedupon the upper end of the battery by inserting the sleeve portion 18 of said cap or dome downwardly within the upper end of the cylinder or carton 12 with the vertical members of the slots 19 passing downwardly over the ins" or rivets 17, after which the cap or ome will be ylocked in position by givmg it a partial turn Aso as to carry horizontal portions of the slots 19 upon. the pins or rivets 17.'

In my construction of electric battery lamp I preferabl employ the lamp 16 asthe means for ma ing and breaking the circuit or as a switch. When the lamp 16 is l screwed upwardly to a-slight extent so as to free the lower terminal thereof from the upper end of the cap 26, the circuit will be broken, because then the lower vterminal of the lamp is not in electrical connection with the positive element 28 of the battery. When it is .desired to complete the circuit and cause the lighting of the lamp, the bulb 16 will be screwed downwardly until its lower terminal engages the cap.26,.where upon the circuit will be completed and the lamp will light. Y

The pasteboard cylinder or carton 12 will preferably be covered over by an ornamental paper or the like 29 so as to add a nish to v the article and renderit suitableto be placed' on a dining table or elsewhere as a candle lamp. The lower end of the battery is broad and serves as a base on which the 'candle lamp may stand without the requirement of theexpensive'stands at present in use in connection with candle lamps. The battery composed of the vertical cells 10, 11 should be tightly held by the cylinder or carton 12 so as not to at any time, even in the absence of the dome or cap, slide through the same. In the present instance the cylinder or carton 12 not only tightly fits around the battery cells, but is further secured with relation thereto by .the conducting wire or strip 20, which in itself will prevent the battery cells from slipping through the cylinder or carton 112.

In Fig. 6 I illustrate a modified form of l cap or dome to be superimposed over the battery and engaged with the pasteboard cylinder or carton 12. The carton 12 of Fig. 6 is provided with the conducting pins or rivets 17 hereinbefore` described, and the cap or dome, numbered 30 in Fig. 6, is formed with a depending skirt portion 31 having bayonet slots to engage the ins 17, the same as the cap or dome 13 is astened in position. In the construction shown Vin Fig. 6 the cap or dome 3()v is dished downwardly at its upper end, as at 32, to represent a candle which has been partly con- -sumed or to imitate the upper end surface of a wax candle which has been burned down at its upper tapered end by use. The cap or dome 30 is formed with a depending threaded metal sleeve 33 to receive the lamp 34 and enter into electrical engagement with the side 'terminal thereof. By reason of the dishing downwardly of the upper end of the ca or dome 30, the lower terminal of the amp -34 may directly engage the positive element 28 of the battery cell 11, and by reason thereof the conductive filler shown in Figs. 1 and 3 may be omitted, said filler being required because of the' elevation of the lamp 16 in Fig. 3- from the Dositive element 28 of the battery cell. The circuit in the construction shown in Fig, 6

lll

lll

Le'mevc is -made or broken by screwing theflamp'at against the positive element 28 'or upwardly from engagement therewith.

In both forms of my invention I provide a candle lamp of desirable character and dispense withexpensive stands for the' same and also avoid the necessity for vspecial switches in making and breaking the cir'- cuits, since I utilize the lamp .bulb itself for that purpose. The cap or dome 13,;shown in Fig. 1, is an approximate imitation of the upper end ofawax candle which .has not been in part, consumed, whereas 'the cap or dome shown in Fig. 6 is in approximatey imitation of the upper end of-a Wax candle which has been in part consumed by use.

In both formsof my invention ,I propose that the cap or dome portion thereof shall be of metal and applied to a new battery whenever a battery in use has become exhausted, it being my purpose that when a battery becomes exhausted, it may be thrown away and replaced by a new'battery of the same kind,fto which the candle features described' may be readily attached.v

An obvious modification of my invention and wholly embodying the same would consist in merely reversing the batteryvor turning it upside down .within the carton 12, in

which event the lamp bulb when screwed downwardly would pass into electrical connection'with the. negative pole of the then upper cell and the conductor 20 at its lower end would be connected with the opposite or positive pole of the then lower cell. Y

My invention admits of modification in the details ot its several parts, and henceI do not confine r' the invention to all 'of the details shown and. described, further than the appended claims may require, and desire to receive adequate protection'for the same.

What I claim as my invention and desire to secure by Letters-Patent, is

1. An electric battery lamp of the character described, comprising a-vertical plural cell battery,l a non-conductive durable carton which receives said cells endwise and snugly encloses them and extends above the upper cell, leaving a-subst'antial space within the upper end of said carton above the battery, a removable conductive cap having a skirt portion snugly fitting within the upper end lof lsaid carton above the battery,
